STMicroelectronics Voltage Regulator 40V 6.5mA Quiescent Current SO 8-Pin L78L12ACD13TR

STMicroelectronics L78L12ACD13TR is a professional-grade voltage regulator designed for fixed positive voltage regulation tasks. It supports a maximum input voltage of 40V and operates with a quiescent current of 6.5mA. The component is surface-mounted using an SO package with 8 pins, dimensions of 5mm by 4mm by 1.5mm, and is designed to maintain performance up to 125°C operating temperature.

The L78L series regulators are built to withstand overheating and overcurrent conditions through internal current limiting and thermal shutdown, making them essentially indestructible. When an adequate heat sink is applied, these regulators can deliver output currents up to 100mA, suitable for various electronic applications including local and on-card voltage regulation. This regulation helps eliminate electronic noise and distribution problems common in single-point regulation schemes.

Furthermore, the series can be integrated with power pass elements to create high-current voltage regulators. The L78L series acts as an efficient replacement for zener diode/resistor setups, offering improved electrical characteristics such as lower quiescent current and noise generation.

Common applications for the L78L12ACD13TR include embedded systems, power supply modules, and electronic circuit boards requiring reliable fixed voltage regulation within industrial, commercial, and laboratory contexts. This regulator contributes to robust and stable power management essential for sensitive electronic components.

The L78L series includes three-terminal positive voltage regulators with current limiting and thermal shutdown features. Output current capability up to 100 mA with proper heat sinking. Surface mount SO package with 8 pins and compact dimensions.

Maximum input voltage rating of 40V ensures adaptability to a wide voltage range. Quiescent current of 6.5mA supports efficient power usage and low noise operation. Durable operation at temperatures up to 125°C. Ideal for replacing zener diode/resistor combinations for better performance.
